Summary

The paper studies the combined free and forced convection in a rotating, viscous, incompressible fluid confined between two parallel porous plates. Assuming that the temperature varies linearly along the plates and the pressure gradient maintained uniform over the planes parallel to the plates, the velocity, temperature and the stresses are calculated analytically. Their behaviours for different values of the parameters viz., the Hartmann number, the Grashoff number and the suction parameter etc., are discussed graphically giving out the interplay between the various forces.

Zusammenfassung

In dieser Arbeit wird die kombinierte freie und erzwungene Konvektion in einem von zwei parallelen, porösen Platten eingeschlossenen, rotierenden, viskosen, inkompressiblen Fluid untersucht. Unter der Annahme einer linearen Temperaturverteilung längs der Platten und eines auf zu den Platten parallelen Ebenen gleichförmig gehaltenen Druckgradienten werden die Geschwindigkeit, Temperatur und die Spannungen analytisch berechnet. Ihr Verhalten wird für verschiedene Werte der Parameter, das sind die Hartmann-Zahl, die Grashoff-Zahl und der Absaugungsparameter und andere graphisch diskutiert, wobei die gegenseitige Beeinflussung der verschiedenen Kräfte aufgezeigt wird.
